FAQ

What is the lug width of the Nomos Glashütte Orion 321.S1?

The lug width of the Nomos Glashütte Orion 321.S1 is 17mm. This is a specific, non-standard measurement that requires precise strap selection. The measurement is taken between the inner shoulders of the lug bar.

Which strap is best suited for the Nomos Orion 321.S1?

For the 321.S1 we recommend alligator or vegetable-tanned calf leather, which emphasise the Bauhaus minimalist philosophy of the white lacquer dial. Cognac alligator or burgundy calf create elegant warm contrast. A navy NATO offers a coherent sporty interpretation. FKM rubber is ideal for robust daily wear.

How do you change the strap on the Nomos Orion 321.S1?

The 321.S1 strap is changed by removing the spring bars that connect the lug to the case. Use a spring bar tool to gently lever the lug, extract the bar, remove the old strap and insert the new one on the same bars. The operation requires precision to avoid scratching the case.

Are aftermarket straps compatible with the Nomos 321.S1?

Yes, any strap with a 17mm lug width is compatible with the 321.S1. It is essential to verify this measurement before purchase. Straps in alligator, calf, shell cordovan, NATO and rubber are all available in the 17mm configuration. The craftsmanship of the aftermarket strap further elevates the aesthetic experience.

How long does a leather strap last over time?

A vegetable-tanned leather strap (alligator, calf, shell cordovan) typically lasts 5-7 years with moderate use, up to 10 years with conscious maintenance. The patina that develops over time is part of the dignified ageing of the material. Durability depends on frequency of use, exposure to moisture, and periodic care with specific products.
